Embodiment Construction
[0022]FIG. 1 shows an optical switch matrix system 100 for selectively adding and dropping channels from a transmission medium 120. The system 100 includes an optical switch matrix 102 having four ports: input port 104, output port 106, add port 108 and drop port 110. The input port 104 is optically coupled to a demultiplexer 112 for receiving input channels 104a-104f from the transmission medium 120. The output port 106 is optically coupled to a multiplexer 114 for transmitting optical channels 106a-106f onto the transmission medium 120. The add port 108 is optically coupled with the optical switch matrix 102 for inputting added channels 108a-108e that are connected to different clients. The drop port 110 is optically coupled with the optical switch matrix 102 for transmitting drop channels 110a-110e, possibly for further processing.
[0023]Both the multiplexer 114 and the demultiplexer 112 are optically coupled with the transmission medium 120. The transmission medium 120 can includ...
